Here at Scorpius Tactical we have one more left of our Sig 516 Gen 2 Upper, excellent upper if like to run suppressors! 

The SIG516 14.5" upper allow operators to upgrade their current AR-15/M16/M4-type rifles from direct gas impingement systems to the SIG SAUER advanced short-stroke pushrod system. This advanced operating system reduces carbon fouling, excessive heat and unburned powder in the action, ensuring reliability and function that is unmatched. A standard 5.56mm NATO chrome-lined chamber and bore ensure reliable function in any environment. Barrels feature an A2 flash suppressor and are threaded 1/2 x 28 TPI, allowing the SIG516 to adapt to a number of aftermarket accessories and suppressor mounts.

Unlike the original 516 uppers, these uppers omit the standard SIG SAUER branding.
